## What makes a great LinkedIn comment

- React to a specific detail of the post rather than a generic "Thanks for sharing".
- Add value: an experience, a nuance, a question that keeps the conversation going.
- Keep it short and readable: 1 to 3 sentences are often enough.
- Be among the first to comment on your prospects' posts to maximize visibility.
- Keep your voice: a comment that sounds like you converts better than a generic one.

## Frequently asked questions

### Are AI-generated comments detectable on LinkedIn?

LinkedIn doesn't flag a comment "because it was written by AI". What can be a problem is large-scale automation. Here, you generate a draft, review it, tweak it and post it yourself: that's the safest use.

### Is it compliant with LinkedIn's rules?

Yes, as long as you keep it human: a generated comment that you review and post manually is a comment you write with assistance. What breaks the rules are tools that automate the act of commenting with no human involvement.

### How many comments per day should I leave?

There's no magic number. Aim for consistency and relevance over volume: 5 to 15 quality comments per day, on targeted posts, beat 50 generic ones.

### Is it better to comment or send DMs?

Both are complementary, but commenting is less intrusive and builds your public visibility: you appear to the whole audience of the post. The DM comes later, once the person knows you through your comments.

### Is the tool really free and no-signup?

Yes. You can generate up to 10 comments per day without creating an account. For unlimited comments personalized to your style, upgrade to LinkHub.
